Reaction Steps
To the THF solution of triphenylphosphine (260 mg, 3 eq.), azodicarboxylic acid diisopropyl ester (0.195 ml, 3 eq.) was added and the mixture was stirred at room temperature for 1 hr. Thereafter, 8-(tert-butyldimethylsilanyloxy)-6,6-dimethyl-11-oxo-6,11-dihydro-5H-benzo[b]carbazole-3-carbonitrile (Compound A10, 138 mg, 0.331 mmol) and methanol (1 ml) were added and stirred overnight. The reaction solution was purified by HPLC to obtain the target compound (44.8 mg, 41%).
